On June 15, 2026, Anthropic splits programmatic Claude usage from your subscription. Agent SDK calls, claude -p headless mode, and third-party Agent-SDK tools now draw from a separate monthly credit pool: $20 on Pro, $100 on Max5x, $200 on Max20x. Once that pool is exhausted, you pay standard API rates.
Most users running terminal-wrapper tools will not notice. A specific category - IDE tools that route through the Anthropic API, and Agent SDK automations - will see real cost changes. Here is the full map.

Verdicts last verified: 2026-05-13
How I verified this: I read each project's README and docs to confirm whether it spawns claude as an interactive subprocess or routes through the API/Agent SDK. The verdict for Cursor and Windsurf is also consistent with their public forum discussions and model pricing pages.
what actually changed
Anthropic's official announcement is direct: "Starting June 15, 2026, Claude Agent SDK and claude -p usage no longer counts toward your Claude plan's usage limits."
The split is between two buckets:
interactive: you (or a tool) runs claude in a terminal and interacts with it. This is unchanged. Your Pro or Max subscription covers it.
programmatic: code calls the Agent SDK, uses claude -p (headless mode), or routes through a third-party integration that wraps the SDK. This now draws from the separate monthly pool - and the pool is finite.
The pool sizes: Pro gets $20/mo, Max5x gets $100/mo, Max20x gets $200/mo. After that, standard API pay-as-you-go rates apply. This is not theoretical - it affects anyone running Cursor with a BYOK Anthropic key, Windsurf with API billing, OpenClaw, Claude Code GitHub Actions, or any CI pipeline using claude -p.
tool by tool
Cursor routes Claude through Anthropic's API. There is no subscription passthrough - BYOK means API billing, and after June 15, that API billing draws from the new programmatic credit pool. See also Pane vs Cursor/Windsurf.
Windsurf uses per-token API billing on its backend. Their model docs show explicit input/output cost pricing. BYOK Anthropic keys are API-routed and hit the new pool after June 15.
Conductor is disputed. Their landing page states it "uses Claude Code however you're already logged in. If you're logged into Claude Code with an API key, Conductor will use that too." That implies subscription passthrough in default usage. However, Theo Browne reports Conductor among tools affected by the June 15 change. The two claims conflict. If you rely on Conductor with a Pro or Max subscription, verify your usage path before June 15 - either by checking the app's auth flow or by watching for unexpected programmatic-credit deductions.
T3 Code is affected. Theo Browne, T3 Code's author, lists it directly among the tools whose Claude usage is affected by the June 15 split. Author claims about their own product carry weight - take this as authoritative.
Zed is affected. Zed's AI features call Claude through the API rather than spawning the local CLI, so they fall on the programmatic side of the split. Reported by Theo Browne alongside other API-routed tools.
Jean is affected per the same source. Like other tools that wrap Claude programmatically rather than spawning the interactive CLI, Jean draws from the new programmatic credit pool starting June 15.
Claude Squad is not affected. Their README states "The default program is claude and we recommend using the latest version." Go-based terminal manager, no -p flag, pure interactive subprocess in tmux.
Vibe Kanban is not affected. Per their docs, it supports Claude Code via subprocess invocation - it delegates to the user's installed Claude Code CLI rather than calling the API directly.
Emdash is not affected. The Electron app spawns CLI agents as subprocesses in worktrees, supporting 23+ CLI agents in a provider-agnostic way. It delegates to the user's installed Claude Code CLI.
Superset is not affected. They describe themselves as: "Orchestrate swarms of Claude Code, Codex, and more in parallel. Works with any CLI agent." Subprocess invocation throughout.
Recon is not affected. Per their README: "Each Claude Code instance runs in its own tmux session." Launch commands use claude --model sonnet directly.
Crystal is deprecated as of February 2026 - the project page now reads "Crystal Is Now Nimbalyst." Moot for most purposes.
OpenClaw and Claude Code GitHub Actions are both explicitly named in the @ClaudeDevs announcement thread (Anthropic's official dev team account) as Agent-SDK-based tools that will draw from the new programmatic credit pool.
Any custom claude -p script or CI pipeline using headless mode is also affected. Headless = programmatic = new pool, regardless of what wrapper is calling it.
what to do
if you use Cursor or Windsurf with a BYOK Anthropic key: your costs change on June 15. The programmatic pool is small - $20/mo on Pro covers roughly 1-2 heavy coding days at current API rates. After that you pay API rates on top of your existing subscriptions. Either budget for the overage or evaluate whether a terminal-wrapper tool covers your workflow. See the comparison.
if you use a terminal-wrapper tool (Pane, Claude Squad, Vibe Kanban, Emdash, Superset, Recon): you do not need to do anything. Your tool spawns claude interactively. The June 15 change does not apply to interactive usage. Your subscription works exactly as before.
if you run Agent-SDK automations or CI pipelines with claude -p: plan around the monthly pool cap. Pro's $20 pool is thin for any meaningful CI usage. Max20x's $200 pool is more workable but still finite. Either upgrade your plan tier, cache aggressively, or move to direct API billing and treat the cost as infrastructure spend rather than a subscription benefit. Anthropic's help center has the full breakdown.
If you want a terminal-wrapper agent manager that's cross-platform and open source, Pane is one option. It runs claude interactively in named terminal panes - unaffected by the June 15 change. More on using your Claude subscription for coding agents.
